PREPARATION OF A KAOLINITE- POLYACRYLONITRILE INTERCALATION COMPOUND

The intercalation complex involving the layer silicate kaolinite and organic compound is studied through the application of infrared absorption spectroscopy and X-ray powder diffraction.The acrylonitrile can be intercalated between the layers of kaolinite by displacing intercalated ammonium acetate from kaolinite/ammonium acetate complex.The XRD pattern showed that the layer interval of kaolinite increased.The IR spectra provide evidence that the inner-surface hydroxyl groups of kaolinite are hydrogen bonded to intercalated DMSO molecules.When there is a initiator,the acrylonitrile monomer can be polymerized between the layers.
